2 Claims. (Cl. 103-218) This invention relates to a pump mount and particularly to a swivel mount for mounting an irrigation pump so that the pump casing may be readily moved for removing the pump from the water so that it may be serviced, repaired or otherwise taken care of.

In the utilization of irrigation pumps to pump water from rivers, lakes or other sources of water onto the nearby land it has heretofore been customary to provide pump foundations in the stream or lake usually by utilizing a plurality of piles driven into the bottom of the body of water and to mount the pump motor on the foundation with the pump submerged in the water. This has required a large amount of fairly heavy work from barges, piers or other expensive supports. Also, repair Work on the pump or its construction frequently requires the same utilization of piers, barges or other means to approach the pump as Well as frequently requiring the necessity of dismantling the pump in order to get it out of the water to operate on it. The present invention provides a swivel mount for irrigation pumps which can be mounted on the dry land adjacent to the shoreline and the pump mounted for both vertical and horizontal pivotal action so that the entire pump may be assembled on the dry land and pivoted about the mount to be lowered into the water where it may be held by a suitable cradle or other support. Likewise in the event of repair the structure may be swivelled onto dry land or other firm support so that the repairs may be conveniently and cheaply made. The setting or removal of a pump requires only the service of a crane for a few minutes in order to lift the pump and place it in the desired position.

Heretofore when such pumps were utilized in navigable bodies of water it has been necessary to provide dolphins or other protective structures about the pump foundations in order to protect them from damage by navigation on the body of water. With the present invention the pump may be placed so close to the shoreline that there is little practical necessity of providing the protective dolphins or if some such protection must be supplied only one side of the pump will need to be protected. Further, in the event of low water the angular inclination of the pump tube may be changed to lower the pump into the water so that continuous pumping operation may be maintained without the necessity of disturbing the mounting.

it is accordingly an object of the invention to provide an improved pump mount.

it is a further object of the invention to provide a swivel mounting which allows the pump to be moved in vertical and horizontal planes.

It is a further object of the invention to provide a pump mount which may be placed on dry land adjacent to the water.

It is a further object of the invention to provide a pump mount which will allow the pump to be assembled on dry land and moved as a unit into pumping position.

Other objects and many of the attendant advantages of the present invention will be apparent from the follownited States Patent l 2,749,846 Patented June 12, 1956 ing detailed description taken in conjunction with the accompanying drawings, in which:

Figure 2 is a top plan view of the pump mount;

Figure 3 is a rear elevation of the pump mount; and

Figure 4 is an enlarged sectional elevation of the mount according to the invention.

In the exemplary embodiment according to the invention an irrigation pump usually of the rotary type is mounted in a pump casing it) which is in turn mounted on the lower end of a casing 12 which is preferably provided with a plurality of sections so that any desired length of casing may be assembled. A suitable screen 14 is mounted around the pump to prevent the entrance of trash or other material thereinto. A driving motor 16 herein shown as an electrical motor is mounted at the top of the pump casing 12. Casing 12 is provided with a plurality of crossheads 18 in which is mounted a housing 20 through which extends a pump rod 22. Pump rod 22 is connected to the motor shaft 24- by means of a suit able threaded collar 26. Guide bearings 2b are provided between the cross members 18 and the shaft 22 and preferably the housing 20 provides an oil sheath for lubrication of the shaft and the pump. in order to supply lubricant to the bearings 28 a reservoir 30 is communicated with the bearing 23 by means of an oil tube 32. As is customary the casing 12 is secured to a pump mount plate by any suitable means such as Welding and the pump motor is also connected thereto by any suitable means such as the screw fasteners 33. Reservoir as may be supported on a tubular member 32 by means of a bracket which connects the tubular oil feed to the pump mounting plate 36.

The mounting proper for the pump comprises a pair of piles and 52 which are conveniently mounted by driving the same on the shoreline adjacent to the water line. In the event the streams are subject to overflow the piles 50 and 52 should be of sufiicient height so that the top of the piles will protrude from normal high Water. A top member or crosshead 54 is constituted of a channel member with the web 56 contacting the top of the piles 50 and 52 with the flanges 58 and 61 extending downwardly alongside the piles 56 or 52. Securing blocks 62 and 64 are inserted between the depending flanges 5S and respectively and the sides of the piles 50 and 52. Securing blocks 62 and 64 are preferably secured to both the piling and the crosshead by any suitable means such as welding. Rigidifying braces in the form of triangular members 66 are secured between the crosshead 5d and the piles 50 and 52 preferably by welding. Pin 68 may be placed in one of the piles such as 52 to facilitate climbing from the ground to the top of the piling. Also a platform 70 may be mounted and secured to the crosshead 54- to provide the space for an operator to stand on the top of the mounting for adjusting the pump mount or when the oil needs to be replenished or other purposes.

A base mounting plate 72 is secured on the crosshead 54 and is preferably constructed as a channel-shaped member with the web 74 in contact with and preferably welded to the web 56 of the crosshead. The flanges 76 and 78 extend upwardly to embrace the sides of a cylindrical base member 50 which is preferably constituted as a substantially cylindrical outer shell 8-2 having ends 84 and 86. Filler members 88 and 9! are provided between the upstanding flanges 76 and 7S and the outer drum 82 and are preferably welded in place to rigidly secure the base to the channel. Rigidifying braces 92 are welded or otherwise rigidly secured between the base and the channel members so that the base is rigidly and properly supported thereon. The web 56 is provided with an aperture 94 while the web 74 is provided with an aperture 96, the end 86 is provided with an aperture 98 and the end 84 is provided with an aperture 100 and an upstanding shaft or axle 102 extends vertically upward therethrough having a head 104 rigidly attached thereto by suitable means such as welding and preferably being secured to the web 56 by welding. A drum or head 1% constitutes a cylindrical member 168 having a bottom end 110 and a top end 112 having apertures 114 and 116 respectively therein with a tubular bearing sleeve 118 rigidly mounted therein. The bearing sleeve 1.18 is adapted to be journaled on the shaft 102 and the top of the shaft 102 is provided with threads 12% so that a nut 122 may be screwed thereon for securing the head or drum 106 in position on the base 80. A yoke member 124 embraces the top or drum 106 and secured thereto by any suitable means such as welding and the ends extend laterally therefrom to provide ears 126. The laterally projecting ends of the ears 126 are provided with horizontally aligned apertures arranged in spaced apart relation. The pump mounting plate 36 is provided with a substantially tubular connector member 128 adapted to fit between the ears 126 and is secured thereto by means of a pintlc pin 130.

In the utilization of the pump mount the piles 50 and 52 are placed in any desired location adjacent to a body of water and of such height that at high water they will extend beyond the water surface. Preferably the yoke 124 will be hingedly connected to the plate 36 after which the device will be lifted by a suitable crane and the drum 1% placed on the upstanding shaft 102 after which the nut 122 will hold the device in assembled relation. A suitable saddle or support 140 may be placed on the bank any place adjacent to the body of water and may be either adjustable or not as may be desired.

A take-oft connection 142 may be supplied in any point along the casing 12 and connected to an irrigation system by means of a separable coupling 144.

When it is desired to operate on the pump for any reason the detachable coupling 144 is disconnected and the entire pump structure is raised and swivelled about the pump so that the pump 10 will be deposited on dry land so that repairs or adjustments may be readily made therein. It will be apparent that only for a few minutes is it necessary to utilize the crane to lift the pump either into or out of the water as may be desired.

In the event of extremely low water a place may be dredged under the pump structure and the saddle 140 either removed or adjusted so that the pump may be located at an angle or acute angle with respect to the piles S and 52 so that the pump may be lowered deeper into the body of water to continue the pumping operation at the low water level. It will be apparent that the present invention provides a simple and efficient swivel mount by which an irrigation pump may be readily located for positioning either in or out of the body of water so that repairs and adjustments may be made Without the necessity of expensive piers or the utilization of expensive barges or other equipment to control the same. Likewise, it will be apparent that the present invention also provides a pump structure in which the pump may be readily handled by means of a crane and the crane immediately released for other purposes.

While for simplicity of description a preferred embodiment of the invention has been shown and described according to the best present understanding thereof, it will be apparent to those skilled in the art that changes and modifications may be made in the construction and arrangement of parts thereof without departing from the true spirit of the invention.
